Thanks to recent warm temperatures and favorable winds, Greater Scaup (Aythya marila) like those shown here are now on the move back to the north, and during the past couple of weeks their numbers have been growing across the region. While you can find some throughout the winter in open areas on large bodies of water such as Lake Erie, most members of this species migrate south to evade the cold. We have been able to enjoy several thousand – probably 5,000 or 6,000 and maybe more – in the waters of Long Island Sound off Stratford Point. Most stay rather far offshore and away from...

“The animal kingdom relies on staggering evolutionary innovations to survive winter.” Bernd Heinrich renowned biologist and author – made this statement in his bestselling book entitled “Winter World”. The Wood Frog (Rana sylvatica) is a true embodiment of this statement; these tiny amphibians can survive for weeks with an incredible two-thirds of their body water completely frozen—to the point where they are essentially solid frogsicles! The adaptation that enables this remarkable feat is known as a cryoprotectant – a substance that prevents damage to cells and tissues during...

Here is a recent photo of a male House Finch (Haemorhous mexicanus) on a snowy afternoon. The beautiful red shades of this guy really stand out against the drab surroundings, and their cheery songs can already be heard here in February on some of the warmer, sunnier days. It is one of the first signs of “spring” as the days began to grow longer. The Purple Finch (Haemorhous purpureus) is a similar species and often confused with the House Finch, especially because both enjoy coming to backyard bird feeders. Roger Tory Peterson described the Purple Finch as having been...
